Ishikawa and Schierholtz, both 30, are good friends and were teammates on several Giants minor-league teams, Ishikawa turning pro in 2002 and Schierholtz in 2003. Both played on the Giants' 2010 championship team, each starting Game 4 of the World Series, the game Madison Bumgarnerthrew eight scoreless innings.

Schierholtz is the godfather of Ishikawa's youngest child, son Jordan, and they were in each other's weddings.

"I'm excited for him. He's a good fit as a left-handed hitter with a little pop, a speed guy who can play great defense," Ishikawa said.

Dropped by the Cubs, Schierholtz signed with the Nationals last week and played four Triple-A games before his promotion. He takes the place of Nate McLouth, who's lost for the season after shoulder surgery.

A day after his first big-league homer highlighted Panik's four-hit game, he received Bochy's lineup card from clubhouse manager Mike Murphyand said he received a lot of congratulatory texts from family and friends, along with his coach at St. John's University, Ed Blankmeyer.

Briefly:Angel Paganwas back in the lineup after exiting Friday's game with a tight calf. ... Bochy is two wins shy of his 1,600th win. Tommy Lasordawon 1,599.
